Don't do full type parameters erasure in PromisedValue::materializeAt

The only case when erasure matters in a context of materialization of
`PromisedValue` is when the type is a type parameter which upper bound
is an inline class. Since `PromisedValue::materializeAt` is a hot spot
and `eraseTypeParameters` is an expensive operation, we should not do
type erasure in other cases.
